What is pressure?
|
the result of a force distributed over an area
|
|
What are the units of pressure?
|
Pascals (Pa)
|
|
What causes gas pressure?
|
collisions between particles of a gas and the walls of the container
|
|
What 3 factors affect gas pressure?
|
temperature, volume, number of particles
|
|
How does temperature affect gas pressure?
|
Raising the temperature of a gas will increase its pressure if the volume of the gas and the number of particles are constant.
|
|
How does volume affect gas pressure?
|
Reducing the volume of a gas increases its pressure if the temperature of the gas and the number of particles are constant.
|
|
How does the number of particles affect gas pressure?
|
Increasing the number of particles will increase the pressure of a gas if the temperature and the volume are constant.
